ABSTRACT:
Provided herein is a system for using a cleaning web in an electrostatic printing process to provide a uniform and thin wax layer on the fuser roll and thereby minimize print history effects, reduce triboelectric voltages on the fuser roll and provide uniform and improved release of the toner from the fuser roll. The application of this beneficial thin film to the fuser roll is accomplished by impregnating the cleaning web with a wax material that is substantially the same as the wax material in the toner used in the system. This impregnated wax, therefore, has the same release and triboelectric properties as the wax in the toner and therefore will not attract residual toner but will rather repel it.
